IODP Expedition 397 Section-half images

Digital section images were taken of the flat face of split cores on the Section Half Imaging Logger (SHIL) using a linescan camera at a resolution of 20 lines/mm (50 micron pixels). Cores were imaged as soon as possible after splitting to minimize color changes that occur through oxidation and drying. The SHIL produces TIF files as well as reduced-size JPG files. The TIF files are not kept online but users may request them from the IODP-JRSO Data Librarian.采用线扫描相机，在断面半芯成像测井仪（Section Half Imaging Logger，SHIL）上对劈开岩心的平整断面拍摄数字断面图像，成像分辨率为20线/毫米（像素尺寸50微米）。岩心劈开后将尽快完成成像，以最大限度减少因氧化和干燥引发的颜色变化。该断面半芯成像测井仪（SHIL）可生成TIF格式文件与缩小尺寸的JPG格式文件。TIF格式文件不提供在线留存，但用户可向IODP-JRSO数据馆员申请获取此类文件。
